       2. The electric range according to  claim 1 , wherein a height of the first member corresponds to the predetermined first distance between the lower surface of the case and the drive circuit. 
     
     
       3. The electric range of  claim 1 , wherein the at least one air guide includes a middle portion that covers at least a portion of the drive circuit. 
     
     
       4. The electric range of  claim 3 , wherein the middle portion of the air guide has a U-shaped cross-section and both sides of the middle portion are disposed in contact with the drive circuit. 
     
     
       5. The electric range of  claim 3 , further comprising:
 a heat sink disposed over at least a portion of the drive circuit, wherein the heat sink is disposed inside of the middle portion of the at least one air guide. 
 
     
     
       6. The electric range of  claim 1 , wherein a second end of the at least one air guide is disposed at least one of adjacent to or at least partially surrounding the at least one second through hole. 
     
     
       7. The electric range of  claim 6 , wherein the second end of the at least one air guide adjacent to the at least one second through hole has a curved shape. 
     
     
       8. The electric range of  claim 6 , wherein a first connecting portion is formed at the second end the at least one air guide adjacent to the at least one second through hole, and wherein the first connecting portion passes through the at least one second through hole to couple the second end of the at least one air guide to the case. 
     
     
       9. The electric range of  claim 8 , wherein the first connecting portion has an extended portion that extends through the at least one second through hole and a bent portion that extends at an angle from the extended portion in parallel to an outside of the lower surface of the case. 
     
     
       10. The electric range of  claim 1 , wherein at least one connecting portion is formed that extends laterally from the first end of the at least one air guide disposed adjacent to the at least one air blowing fan, and wherein the connection portion has a coupling hole to couple the at least one air guide to the case. 
     
     
       11. The electric range of  claim 1 , wherein the at least one air guide has an open lower side. 
     
     
       12. The electric range of  claim 1 , wherein the first end of the at least one air guide disposed adjacent to the at least one air blowing fan has an opening that extends in a vertical plane. 
     
     
       13. The electric range of  claim 12 , wherein a second end of the at least one air guide adjacent to the at least one second through hole has an opening that extends in a horizontal plane. 
     
     
       14. An air guide for an electric range, comprising:
 a housing having a hollow inside; and 
 a first member formed on a lower side of a first end of the housing, wherein the first end of the housing is configured to receive air output from an air blowing fan of the electric range and a second end of the housing is configured to discharge air output from the air blowing fan, wherein the second end of the housing has a curved shape, wherein the first member is configured to prevent air output from the air blowing fan from flowing into a space between a lower surface of a case of the electric range and a drive circuit in the case of the electric range, wherein the first member has an inclined shape, wherein the first member is formed at a lower end of the one end of the housing, wherein the case has a boss that protrudes upward from the lower surface of the case, and wherein a first end of the first member is disposed to contact the lower surface of the case, and a second end of the first member is disposed to contact an end of the drive circuit disposed on the boss. 
 
     
     
       15. An electric range comprising the air guide of  claim 14 . 
     
     
       16. An electric range, comprising:
 a case having at least one first through hole and at least one second through hole; 
 at least one working coil disposed in the case, and configured to heat an object to be heated; 
 a drive circuit configured to drive the at least one working coil and disposed between the at least one first through hole and the at least one second through hole;
